In finding the perimeter of a triangle, you must add the base (a) to base (b) and the sum will be added to the side (c)
Triangle Perimeter Formula : a (base) + b (base) + c (side)
In finding the perimeter of a trapezoid,you must add the two bases, (a + b) , and the sum will be added to the sum of two sides (c + d)
Trapezoid Perimeter Formula : a (base 1) + b (base 2) + c (side 1) + d (side 2)
In finding the perimeter of a square, you must multiply one side (a) to 4 because squares have 4 sides.
Square Perimeter Formula : 4a or a (side) x 4
In finding the perimeter of a parallelogram, you must added the base (b) to the side (a) then multiply it by two.
Parallelogram Perimeter Formula: 2 (a + b) or base + side x two
I just don't want to ask you on what shape to find the perimeter of a triangle, so here is the complete answer!
